lVlOLD FOR GLASS LAMPS, 8&0.

SPECIFICATION forming part of Letters Patent No. 312,312, dated February 17, 1885.

Application filed June 23, 1884.

(No model.)

To a, whom it may concern:

Be it known that I, JosErH M. WOOD, a resident of Bellaire, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Molds for Glass Lamps, 8m; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to certain improvements in molds for forming glass vessels used for containing oil, such as lampbodies and similar articles; and it has forits object to provide for the formation of adrip-channel around the upper edge of the body, to catch and retain any drippings occurring during the filling of the lamp, and the oil carried up by capillary attraction through the wick and discharged on the outside. This object I attain by the means illustrated in the accompanying drawings, in which- Figure 1 represents a top view of my improved mold; and Fig. 2, a vertical sectional view taken. on the line 00 00 of Fig. 1, showing the position of the glass body in the mold, which, for the purpose of illustration, shows an ordinary lamp-bowl.

The letter A indicates the main portion of the mold, which is constructed in two parts, each having a matrix corresponding in shape to one-half of the lamp-body to be formed. The said parts are hinged together at one side, and on the opposite side are provided with handles A, by which the mold may be manipulated to open and close it.

The top of the mold is provided with an annular recess, B, having an undercut groove, 0, in which is adapted to fit a divided annulus, D, which is provided with a flange, E, the annulus setting in the annular recess and the flange in the undercut groove therein, so that the annulus will be securely heldin place when the mold is closed, and form the top of the mold. The lower side of the annulus is fashioned to conform to the shape of the top of the lamp-body,and so as to produce an upwardlyprojecting rim, F, around the upper edge, to form the drip-channel for the oil. The parts of the annulus are provided with handles G, by means of which they can be manipulated.

In operation the parts of the divided annulus are placed in the undercut recesses in the respective parts of the mold, and the same are partly closed when the body is blown in through the upper aperture, K, the parts of the mold with the annulus being gradually closed together during the operation, so as to compress and solidify the glass and form a compact and perfect article.

Having thus described my invention.what I claim, and. desire to secure by Letters Patent,

In a two-part mold for articles of glassware, the combination, with the hinged parts forming the body of the mold, and provided with handles and undercut recesses near the top, of the divided annulus provided with handles and adapted to fit in the mold, whereby the parts may be closed upon the glass during the operation of blowing in to compact and solidify the article, substantially as and for the purposes specified.

In testimony that I claim the foregoing as my own I hereby at'fix my signature in presence of two witnesses.

IO S. M. WOOD.
